EN 3019:2008 - Aerospace series - Self-locking plate nuts, floating, two-lug, in heat resisting steel FE-PA92HT (A286) - Classification: 1 100 MPa (at ambient temperature)/650 °C

Overview

EN 3019:2008 is a CEN (European) aerospace standard that defines the characteristics of self-locking, floating plate nuts - two-lug - manufactured in heat‑resisting steel FE-PA92HT (A286). The standard covers configuration, dimensions, tolerances, masses, material requirements, designation, marking and the applicable technical specification for these aerospace fasteners. It assigns a strength classification: 1 100 MPa (ambient)/650 °C (maximum test temperature) and is intended for use where high temperature resistance and reliable self‑locking performance are required.

Key Topics and Requirements

  • Configuration and dimensions: Detailed geometry for two-lug floating plate nuts is specified (see Figure 1 and Table 1 in the standard). Includes overall sizes, flange details and permissible tolerances.
  • Material: Nut element and cage material requirements reference heat‑resisting alloys (FE‑PA92HT / A286) and related EN material standards for forgings, sheet/strip and wire. Material selection targets high temperature strength and stability.
  • Strength classification: Designation of strength class 1 100 MPa at ambient temperature with a maximum test temperature of 650 °C - important for component selection in high‑temperature zones.
  • Threading and fit: Uses MJ thread forms and limit dimensions in accordance with ISO 5855‑2; thread surface finish and pitch diameter expectations are included.
  • Self‑locking feature: Specification addresses the out‑of‑round area and tooling marks required to achieve reliable self‑locking performance without compromising thread integrity.
  • Radial float: Radial float allowances are defined to permit limited movement of the nut assembly in all directions as required by aircraft structures.
  • Marking and designation: Marking rules follow EN 2424 (Style N) and the standard includes an example of designation and identity blocks for procurement and traceability.
  • Technical specification: Final technical and acceptance requirements refer to EN 3004.

Applications and Who Uses It

  • Aerospace OEMs and suppliers specifying or manufacturing high‑temperature fasteners for airframe, engine mounts, firewalls and other hot zones.
  • Fastener manufacturers producing two‑lug floating, self‑locking plate nuts in FE‑PA92HT (A286).
  • Design and stress engineers selecting hardware for high‑temperature and vibration‑sensitive assemblies.
  • Quality and procurement teams ensuring component conformity, traceability and interchangeability across the supply chain.
